When my Hollowgrams arrive I can sell you the brand new MK-V rings just pm me and remind me.

Anyone have any tips for the install? The spindle has already been installed (these are a take off, apparently the seller wanted DA 7900 cranks instead). It came with the ceramic BB and the bearing shields as well. Any special washers, etc. I should ask for from my C'Dale dealer before doing the install?

I only want to have one power meter and switch between the two cranksets. Just curious how easy this would be with an SRM (or a Quarq)? I know I need C-Dale specific parts KT012 and KT013 to loosen the crank arms as well as the spindle. Is it as easy as that and then pop on the powerunit? The Quarq requires the power meter is sent to them to be installed, does that mean I won't be able to move it from one bike to another? Both cranks are standard (130) and same crank arm lengths. Thanks for any help guys.

Yes, you will need those tools.

I have not swapped power meters, but I have swapped spyder's on my SI's so I can switch from standard to compact, and vice versa. It's not terribly difficult to remove the piece holding the spider on. I used a large monkey wrench to hold the KT013. It would probably help if you have a vise to hold the crank, though I did not have one.

As for swapping the Quarq or SRM between two cranks, since they are the same length and BCD, it would probably be easier to just swap the entire Right Crank arm, - Quarq and Rings - between bikes than to take off the Quarq and reinstall it on another arm.

I'm currently using an FSA SLK crankset. I have always wanted an SI SL crankset but never saw it to be financially realistic. I found a new SI Hollowgram for a good price, but after a little bit of research I saw that there is a difference between the SI and the SI SL Hollowgram.

For $400 Should I pull the trigger or should hold on for the SI SL crankset which will be about 100g lighter than the SI?

Has anyone got any new info on the new forged hollowgram si? its been coming on the ui2 evo for awhile now and will be on a bunch of models for 2014, someone must know some specs. weight? when it will be available or will it only come on bikes? msrp if they sell it? anything? thanks

Sorry to drag this thread up, but can how fit a pair of Hollowgram SISL (which are BB30) onto a BMC SLR which is BB86? What sort of BB adapter would I need? Or should I just forget about it and get a Lightning crankset in BB86 straight away and avoid the additional adapter weight?
